General Tools Wood Moisture Meter

Introduced at the National Hardware Show was the General Tools Wood Moisture Meter. This meter is specifically designed for any carpenters, cabinetmakers, or other wood workers that are concerned about moisture content when selecting or working with their pieces. This can be incredibly helpful in environments where the humidity is a constant fight and you have to wait for wood to acclimate indoors before using, sealing, joining, or treating the material.


One of the most impressive features on the MMD8P is that has been engineered with the ability to measure the moisture content in 48 different species of wood! Unlike meters that only display a code that you then have to look up, the General Tools Wood Moisture Meter displays the species name along with the code, saving you time. It also features an organic light emitting diode (OLED) screen with temperature compensation. The temperature compensation allows you to take into consideration concerns like moving wood from outside to inside.  The meter will store up to 99 measurements and include data for moisture level, wood species name, ambient temperature, relative humidity, and applied temperature compensation.

Current prices online for this model are running between $170 and $200. The General Tools Wood Moisture Meter comes with a limited 1 year warranty and runs on one 9 volt battery that is included along with a hard case and manual.
